American Indian law

American Indian law: an overview

In U.S. law the term "Indians" refers generally to the indigenous peoples of the continent at the time of European colonization. "Alaska Natives" and "Native Hawaiians" refer to peoples indigenous to the areas occupied by those named states. The terms "tribe" or "band" designate a group of Indians of the same or similar heritage united in a community under one leadership or government and inhabiting a particular territory. Because Indians have increasingly preferred "nation" or "people," the term "tribe" has become controversial. The terms used may vary from statute to statute and case to case as well.

States may recognize particular Indian groups, even if the federal government does not recognize the group. To determine whether a group will be recognized, courts and legislatures examine such factors as the extent of Indian governmental control over individual lives and activities, the extent to which the group exercises political control over specific territory, and the continuity of the group's history.

Federal law recognizes a special kind of Indian sovereign authority to govern themselves, subject to an overriding federal authority. Indian tribes are considered by federal law to be "domestic, dependent nations." Congress enacted this sovereign authority to protect Indian groups from state authority. This sovereign authority extends to Indian tribal courts, which adjudicate matters relating to Indian affairs. The U.S. Supreme Court heard a case in in 2008 concerning the extent of tribal courts' jurisdiction. In Plains Commerce Bank v. Long Family Cattle Co. (07-411), the U.S. Supreme Court reaffirmed a long-held principle that tribes do not have jurisdiction over non-Indians conducting activity on a non-Indian fee simple, even if on an Indian reservation, unless the activity threatens the welfare of the tribe.
